Embodiments of the present invention will be described below with reference to the drawings.

The replacement container according to the present invention is used by detachably mounting a pump, and is used for replacement with a new container when the stored liquid is used up.
The bulk can be reduced.

FIG. 1 shows an embodiment, in which a container body 2 is formed entirely of a synthetic resin, a rear half of a cylindrical body 3 is formed in a thin portion 3a, and a body 3 other than the thin portion is formed. The mouth and neck 4 is erected from the upper surface. Further, a flange 5 extends outward from the upper end of the mouth and neck 4. Accordingly, when the pump is mounted and the stored liquid is used, the internal pressure is reduced and the thin portion 3a is depressed inward, and ideally, the thin portion 3a is deformed so as to finally overlap the inner surface of a portion other than the thin portion. As the degree of the thin portion 3a, specifically, a resin amount of 5 to 4
A thickness of about 0 g is good as a guide, but is not limited to this. The thickness of the body portion 3b other than the thin portion is approximately the thickness of a conventional general synthetic resin container. However,
The upright state can be maintained irrespective of before and after the deformation of the thin portion, and the thickness has a large buckling strength. Further, the body 3 is not limited to a cylindrical body as shown in the illustrated example, and various cylindrical bodies can be adopted.

Since the container 2 is for replacement, the liquid is always stored and the upper end opening is closed. Although the closing of the upper end opening can take various forms, a sealing material 6 may be provided as shown in the illustrated example. When the sealing material 6 is provided, there are a case where a pump having a cutter as described later is used and a case where a pump without a cutter is used. In the former, the pump is made of a material which can be pressed and broken relatively easily. The peripheral part is fixed to the upper surface of the mouth and neck part 4 by an appropriate means such as fusion or adhesion so as not to cause any problem. In the case of the latter, it is preferable to use a method such as an adhesive to releasably adhere and protrude a finger-hanging protruding piece from the edge. In the latter case, it is also possible to provide a cap of a normal form instead of the sealing material.

Further, in the liquid jetting device of the present invention, a pump is detachably mounted on the container body 2 provided with the sealing material 6 as described above, via a connecting member with a cutter that has broken through the sealing material. When the container is replaced, the sealing material is automatically broken and a new container can be mounted so that the liquid can be ejected. Further, in order to make it easier to mount such a connecting member, the connecting member is configured to be screwed down to a screw cylinder detachably provided on the container body to mount the connecting member. The seal material should be relatively easy to press and break, but if the liquid tightness during storage is taken into consideration, the opening of the break is troublesome. Is configured to penetrate through.
